<p>The button is not in a ASP:Panel with a DefaultButton set, it has no OnClientClick attribute, I can see no JavaScript that watches for the Enter key... Why is it firing?</p>
<p>If I create a standard .ASPX page and put a text box and a button on it, run it and hit the enter key, the button is ignored, e.g. the click event doesn't fire. This is the behaviour I expect, but am not getting.</p>

2,013,740 | 2,013,741 | Android Broadcast onReceive method not called from service | <p>I have a service that sends an sms. I have a broadcast receiver that is registered to notify me when the sms has been sent or not sent. The problem now is in the emulator (froyo), everything works fine when an sms is sent and when it isn't. However on my phone (galaxy S i9000, darky rom 9.3), and on my friends HTC with cyanogenmod 7, the service sends the sms but there are no notifications, if i switch my phone to airplane mode and run the app, i received notifications telling me that the messages weren't sent (which is expected). On investigating, I realised that the onReceive method of my broadcast isn't called at all when the sms is sent. In logcat i also realised that in the emulator the smsmager sends the message, on my phone, the SMSDispatcher sends the message and SMSDispatcher is an internal android class that isn't part of the public api so i cant access it. Any ideas?</p>

When it is clicked, it scrolls to a form at the top of the page with the animated style. And as it arrives at top of page, it focuses on the first field in form.</p>
<p>Currently, this is my code:</p>
<pre><code>$(document).ready(function() {

$('html, body').animate({scrollTop: $("#show-form").offset().top}, '500');
$('#first-field').focus();
return false;

<p>What happens is it begins scrolling, then focuses to form field while still in process of scrolling, then returns to last position in scrolling process and continues scrolling up. Instead of being smooth, you can see it cuts back and forth.</p>
<p>How can I tell jquery to wait until scrolling is complete before focusing to the form field?</p>

637,793 | 637,794 | Writing reusable code | <p>I find myself constantly having to change and adapt old code back and forth repeatedly for different purposes, but occasionally to implement the same purpose it had two versions ago.</p>
<p>One example of this is a function which deals with prime numbers. Sometimes what I need from it is a list of n primes. Sometimes what I need is the nth prime. Maybe I'll come across a third need from the function down the road.</p>
<p>Any way I do it though I have to do the same processes but just return different values. I thought there must be a better way to do this than just constantly changing the same code. The possible alternatives I have come up with are:</p>
<ol>
<li><p>Return a tuple or a list, but this seems kind of messy since there will be all kinds of data types within including lists of thousands of items.</p></li>
<li><p>Use input statements to direct the code, though I would rather just have it do everything for me when I click run.</p></li>
<li><p>Figure out how to utilize class features to return class properties and access them where I need them. This seems to be the cleanest solution to me, but I am not sure since I am still new to this.</p></li>
<li><p>Just make five versions of every reusable function.</p></li>

<p>A TextBox should be used to input the guess. As each guess is input, the background color should change to red or blue.

When the user guesses the correct answer, display "Correct!" in a message box, change the Form's background color to green and disable the TextBox.

<p>Above code works but, when my activity gets launched it displays one blank black screen for 1-2 seconds and then it displays the main screen of the activity. </p>
<p>I am doing this check in the <code>onCreate</code> of the activity.<br>
Is there another why of doing this check. </p>
<p>UPDATE:<br>
I don't want to check if Network is connected or not, I want to check if Device has Access to Internet. It may be the case that Device has Network connection but that network connection does not have Internet Access. </p>
<p>Thanks.</p>

<pre><code>$("#id").addClass('selected'); // doesn't work;
$("li" id).addClass('selected'); // doesn't work;
$("#" id).addClass('selected'); // doesn't work;

1,889,839 | 1,889,840 | Search by substring on strings which map to id | <p>What would be the best way to implement search by substring on Strings(around 5000 entity names in application) which map to entityId. </p>
<p>I want to implement it so that I could put searched suggestions to the user as he types in one or more characters.For e.g I would want to be able to suggest all entities starting with his queried substring as he does the search.</p>
<p>Looking forward to store them in the application scope itself to avoid frequent retrievals from DB.</p>
